Food chemical contaminants are a major factor in the cause of foodborne diseases and can do harm to human health. Hence, it is highly desirable to develop robust, easy, and sensitive methods for rapid evaluation of food chemical contaminants. Nanomaterial-based optical aptasensors combined with the advantages of the high selectivity of optical detection… (More)

Antibiotics are able to be accumulated in human body by food chain and may induce severe influence to human health and safety. Hence, the development of sensitive and simple methods for rapid evaluation of antibiotic levels is highly desirable. Nanomaterials with excellent electronic, optical, mechanical, and thermal properties have been recognized as one… (More)
